Application filed March 13, 1912. Serial No. 883,439.

To all wiwm it may concern:

Be it known that I, JOSEPH H. Porn, a citizen of the United States, residing at Hamilton, in the county of Essex and State of lVfassachusetts, have invented certain Improvements in Machines for Operating on Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements in machines for operating upon heels and is herein shown as embodied-in a machine for attaching heels and top lifts to boots and shoes although it may be embodied to good advantage in other types of machine, such for example as heel pricking or heel loading machines.

An object of the invention is to provide automatically acting mechanism for pre senting the blanks in operative position.

In operating a heeling machine the several operations which must be performed manually in attaching the heel blank and top lift are usually divided between the operator who attends to jacking the shoe, moving it into operative position and starting the machine, and an attendant who supplies the nails to the die plate, places the heel blank in its carrier and moves it into operative position and then inserts a top lift and moves that into operative position When it is desired to apply cement to the heel blank after the heel has been attached.

or top lift this operation also falls to the attendant. Ordinarily the operations which the attendant must carry out require a longer time than the operations of jacking the shoe, moving it into place and, starting the machine so that the operator is not enabled to operate the machine continuously as rapidly as he might if the attendant could keep pace with him.

An important object of the invention therefore is to render the presentation, of the blanks automatic so that the attendant will be relieved of these duties and enabled more rapidly to carry out the other necessary operations while the operator is per forming his portion of the work.

An important feature of the invention consists in the provision of a blank carrier movable into the path of the tools for operating upon a heel in combination with an actuator which is placed under stress or tension in the operation of the machine, together with means under the control of the operator whereby the carrier may be released and the actuator permitted to move it to bring a blank into operative position at the proper point in the operation of the machine.

in operating a heel attaching machine it sometimes happens that the operator will desire to cause more than a single stroke'of the drivers or spanker plate to take place upon one blank, as for example, in case a top lift should be improperly positioned in the first instance when it is customary to remove the lift, locate it properly and at tach it by another stroke of the machine and during this operation the presentation of a new blank by the carrier would be detrimental.

'An important feature of the present invention consists in automatic actuating means which are controlled by theprevious provided for rendering the tensioning means inoperative so long as the carrier remains in its normal position but when the carrier has been moved the spring is at once placed under tension in readiness for mechanism; Fig, 3 is a fragmentary plan view of the center portion of the carrier, and Fig. 4 is a detail view in perspective of a portion of the actuating mechanism for the carrier.

The machine comprises a frame 10 provided with a stationary cross-bar 12 in which are formed the driver passages 14 through which reciprocate the drivers 16 carried by the crosshead 18. The crosshead is secured to the upper ends of side rods 20 which may be actuated in any suitable manner, for example, through a lower crosshead connected with an eccentric as shown in the patent above referred to. Mounted in the frame for reciprocation toward and from the crossbar is a jack carriage 21 provided with horizontal ways 22 extending from front to rear in which is slidingly mounted the jack 24. In operating the machine the jack is pulled forwardly in ways and a shoe positioned on it and then pushed rear\\"ardly to bring the heel seat beneath the driver passages 14, the shoe being properly located under the bar 12 by the side gages 26 and rear gages not shown.

The carrier is journaled upon the right hand side rod 20 and comprises a flat plate 28 having four outwardly projecting portions. Upon the lower surface of each of these portions is arranged one of four blank holders. In the normal operation of the machine these blank holders are intended to receive alternate heel blanks and top lift blanks. The carrier plate is cut away at its center and has secured to it four down wardly and inwardly extending arms 30 which at their lower ends, merge into an annular flange 32. The flange 32 rests upon a ring 34 journaled upon the side rod 20 and resting upon the upper end of one journal bearing of the rod 20. The upper surface of the carrier plate 28 is substantially flush with the lower surface of the cross-bar 12, the center portion of which constitutes in effect a die block, and the arrangement is such that when turned into proper position a blank will be properly positioned beneath the driver passages. In order to hold the blank carrier with a blank properly registered in position each holder portion is provided with a notch 36 and a spring pressed locking bolt 38 is mounted in a bracket 40 on one side of the cross-bar '12 and arranged to enter one of the notches as the carrier plate is turned. The corners of the carrier plate are rounded so that the locking bolt 38 will be retracted as the carrier is turned until the notch comes into register with it. In order to retract the locking bolt 38 and permit turning movement of the carrier to take place a hand lever 42 is pivoted on a horizontal axis above the bracket 40 and has suitable connection, as by a pin with the locking bolt as shown in Fig. 1. The lower end of the lever 42 extends into close proximity to the shoe upon the jack so that when the jack is pushed into operative position the hand of the op erator is close to the lever and it can be swung to retract the locking bolt with little effort and no appreciable loss of time.

The portions of the carrier plate which are intended for heel blanks are cut away in order to permit the passage of the drivers while the portions which are intended. for the top lift blanks are solid and act as spanker plates. Each carrier comprises a forked rear gage 44 and a breast bar 46. The rear gage is arranged for adjustment longitudinally of the blank in ways formed on the under side of the carrier and each breast bar has a shank extending at right angles to it and received within a channel plate or guideway 48 secured to the under side of the carrier. The breast bar is yieldingly moved toward the rear gage by a spring 49 extending between an adjustable pin on the carrier and a projecting arm secured to the breast bar. A stationary plate 29 is secured to the side of the frame with its lower surface flush with the carrier 28 and this plate assists the attendant in pre senting heel blanks to the holders below the cut out portions of the carrier plate.

The carrier is turned to present successive blanks by a tension spring 50 connected at one end to one of the arms 30 of the carrier and at the other to the loose ring 34 upon which the carrier rests. The ring 34 is provided upon its periphery with ratchet teeth and is rotated in an intermittent manner by a pawl 52 mounted upon the upper end of a bracket 54. The bracket 54 is secured at its lower end to a sleeve 56 journaled upon one of the side rods 20 and supports the sleeve 56 by its inwardly extending flange 58 which engages a stationary flange 6O projecting outwardly from a tubular nut secured to the machine frame adjacent to the lower end of the journal for the side rod 20. The sleeve 56 and bracket carried thereby are oscillated by a pin 62 set in the side rod 20 and projecting into an inclined slot 64 in the sleeve. The slot extends substantially 90 circumferentially so that each complete reciprocation of the side rod results in an oscillation of the sleeve, bracket and pawl of substantially 90 and return. In the downward movement of the side rod the pawl 52 turns the ring 34 through su stantially 90 in the direction of the arrow in Fig. 3 and thereby places the spring 50 under tension, the carrier 28, to which the other end of the spring 50 is secured, being locked by the bolt 38. Reverse movement of the ring 34 is prevented by a pawl 66 mounted upon a stationary bracket 68 upon the machine frame. Upward movement of the rod 20 moves the sleeve and pawl 52 reversely carrying the pawl to a position adjacent to the next tooth on the ring 34:. In the drawing the machine is represented with the cross-head and side rods moved downwardly from their initial position for about one third of their stroke.

It will be apparent from the foregoing description that in the continuous normal operation of the machine the ring 3% is turned through 90 by the dog 52, then, when the carrier is released, the carrier turns 90 after the ring and in the same direction, the ring is then turned again 90 in the same direction and the carrier follows it when released, and so on indefinitely.

In the machine as described thus far it is apparent that each reciprocation of the side rods will effect a turning movement of the ring 34 of 90 and consequent tensioning of the spring 50, regardless of the turning of the carrier. It is important to prevent more than one tensioning of the spring 50 between two consecutive movements of the carrier as otherwise the spring 50 would be broken if the operator should cause the machine to make two driving or spanking strokes without permitting the carrier to turn.

As one means for preventing the repeated turning of the ring 34L and excessive tensioning of the spring 50, a shield is pivoted upon a horiZontalaXis below the ring 34: and is arranged, at one period in the cycle of the machine, to lie against the periphery of the ring in such position as to prevent the dog 52 from engaging the tooth of the ring. The shield 70 is provided with an upstanding tail disposed in the path of the arms 30 of the carrier and when the carrier is rotated one of these arms. encounters the tail of the shield and turns the shield into an inoperative position in which its end is below the ring 34. The movement of the shield takes place against the action of a spring 72 which tends to throw the effective end of the shield inwardly and upwardly. When the shield has been turned by an arm of the carrier its end moves under the ring 34. which has been caused to advance slightly in the same direction as the carrier until it overlies the shield and the shield is held in inoperative position until the ring is turned sufficiently to carry the narrow portion at the base of one of the ratchet teeth above the shield at which time the spring 7 2 turns the shield into operative position as shown in Fig. 4.. In Fig. 4: the dog 52 is represent ed as making an idle oscillation, having been prevented from engaging a tooth of the ring 34 by the shield 70, and it will be clearly seen from this figure that, when the carrier is permitted to advance, the arm 30 of the carrier will encounter the beveled end of the upstanding tail of the shield and move the shield downward out of the tooth. The stud upon which the shield is mounted is long enough to permit the required in and out movement of the shield.

In the normal operation of the machine the attendant who stands at the rear will supply nails to the passages 14 by the use of a suitable loader and insert successively heel blanks and top lift blanks in the holders of the carrier but need give no attention to turning the carrier to present the blanks in operative position, this operation being effected automatically. In the reciprocation of the side rod 20 occuring when a top lift is spanked the ring 34 is turned and the spring 50 placed under tension in the manner already described, the carrier being held against turning movement by the locking bolt 38. When the operator pushes the jack into operative position preparatory to heeling the next shoe he will strike the end of the lever 42 with the back of his hand thus retracting the locking bolt 38 and permitting the spring 50 to turn the carrier until the locking bolt engages the notch 36 in the arm of the carrier which has been supplied with a heel blank. The machine is set in operation and the attaching nails driven and during this operation the ring 3% is again advanced through and the spring 50 placed under tension. The operator will then swing the hand lever 42 to release the carrier whereupon the top lift blank is swung into operative position and may be spanked upon the heel in the next operation of the machine. In case the operator should desire to cause a second stroke upon one heel blank or top lift and does not permit the carrier to turn the actuating ring 34: remains at rest and the spring 50 is not further tensioned. until after another blank has been presented in operative position.
